PROCEDURE FOR PRODUCTION OF MAGNESIUM AND DIOXIDE OF CARBON OF OXIDE-FLUORIDE MELTS IN BI-POLAR ELECTROLYSER Russian patent published in 2011 - IPC C25C3/04 C25C7/00 

FIELD: metallurgy.

SUBSTANCE: procedure consists of electrolysis at continuous feed of electrolyte with oxide of magnesium and fluoride salts with withdrawal of carbon dioxide through system of out-gassing. Also, electrolysis is carried out in a bi-polar electrolyser with stationary cathode and bi-polar electrodes suspended in electrolyte set off to the stationary cathode for maintaining constant between-poles distances at consumption of anode parts of bi-polar electrodes. Oxide of magnesium and fluoride salts are supplied with compressed air for continuous feed of electrolyte. They are uniformly distributed on surface of electrolyte with extraction of liquid magnesium on a cathode side of the bi-polar electrode. Liquid magnesium is withdrawn into a collecting cell of the bi-polar electrolyser.

EFFECT: raised efficiency, reduced specific power output due to reduced dimensions of electrolyser, raised current output owing to reduced interaction between carbon dioxide and magnesium.
